Twilight Velvet's mane and tail bear a slight resemblance to those of her daughter Twilight Sparkle, and she strongly resembles Lauren Faust's original concept art that was based on G1 Twilight. Night Light shares Noteworthy's color scheme, and appears to be visually based on the G1 German release Rainbow Pony Nachtlicht.

Siblings

Twilight's older brother is named Shining Armor. He first appears in the season two finale A CanterlotWedding as the captain of the royal guards and Princess Cadance's husband-to-be. Prior to his debut, Shining Armor was announced as a part of the then-upcoming Pony Princess Wedding Castle toy set, which comes with him and Princess Cadance.

Extended family

Princess Cadance first appears in the season two finale as Shining Armor's fiancée. She was Twilight Sparkle's beloved foal-sitter when she was a filly, and the two share a special handshake with the accompanying rhyme: "Sunshine, sunshine, ladybugs awake! Clap your hooves and do a little shake!" Through Cadance's marriage to Shining Armor at the end of A Canterlot Wedding - Part 2, she and Twilight become sisters-in-law.
